How to Build meteorological satellite pictures Receiver With $20 electronic device

This “how-to build meteorological satellite pictures receiver” is predicated upon Matt Gray’s project on receiving meteorological satellite image with £8 electronic device. Matt grey is that the one UN agency developed emoji. he's additionally a locality of renowned YouTube videos channel “The Technical Difficulties.”
He discovered that you just will get meteorological satellite pictures directly from the satellite after they pass overhead, by simply employing a $20 free view electronic device and so you'll build your own meteorological satellite pictures receiver!. He received his 1st image on his fourth try.

NOAA fifteen northward 90E at twenty five Jul 2015 16:39:04 time on 137.62MHz, MSA sweetening, traditional projection, Channel A: two (near infrared), Channel B: four (thermal infrared)
How to build your own meteorological satellite pictures receiver?
According to Matt, many yank bureau weather satellites during a polar orbit around Earth, every of which can pass a similar purpose below each twelve hours about. The satellites transmit footage via FM radio at 137MHz. employing a DAB/FM/Freeview electronic device, you'll receive this signal on a pc running code-defined radio (SDR) software, so decipher it into an image to create your own meteorological satellite pictures receiver.

Following things ar required to create a meteorological satellite image receiver at home-

1 A Nooelec R820T USB electronic device ($21 on Amazon).

2 CubicSDR to tune and receive the signal.

3 Soundflower to pipe audio out of CubicSDR into:

4 WXtoIMG that mechanically records once the satellite ought to be overhead, then decodes and processes the image. it'll additionally tell you once the satellites ar overhead next.

5 A two meter little bit of wire crowded within the screw hole at the bottom of the little antenna (not the MCX connector), during a vain conceive to have one thing slightly additional tuned to 137MHz.

Method to create your meteorological satellite pictures receiver:
1. Go outside. You’re attempting to choose up a symptom from area to create your own meteorological satellite pictures receiver. you would like as few things within the approach as doable.

2. Open Soundflower

3. Open CubicSDR tune to the satellite’s frequency (137.xxMHz) with a information measure of

        36kHz.Set audio output to Soundflower (2ch)

4. Open WXtoIMG Make positive the soundcard is about to Soundflower (2ch) in choices-
         Recording Options File->Update Keplers if you’ve ne'er done it before, therefore it is aware         of wherever the satellites File->Satellite Pass List can tell you once to expect the pass

5. Set WXtoIMG to machine record File->Record

6. Watch CubicSDR till you see the information lines fade in.  If the lines aren’t targeted, drag it              within the high left window till they're. they're going to drift over time (This is perhaps thanks            to the Christian Johann Doppler effect).

7. For me, a picture light out of the noise on WXtoIMG once the satellite was on top of twenty               degrees, and looked best once it had reached the best purpose and was on its approach back off.           (I’m forward this can be thanks to buildings/etc interference signal).

8. If the signal was ok, WXtoIMG can method it. Enhancements->MSA Multispectral Analysis         created it seem like a color exposure.
        You might be able to receive alternative things with this setup like FM Radio, ADS-B – The               signal planes broadcast to mention wherever they're and the way quick they’re going or traffic             management signals.

Let us apprehend in comments what did you get when building this meteorological satellite pictures receiver.

Turn your smartphone into three interesting, ususual and useful tools

No comments :
Your smartphone is a very versatile tool. Here are some interesting, unusual and useful things you can make it do.


Got a 'Check Engine' light on your dash, staring at you? In the trade that's called 'the money light.' Wonder what it means? Wonder how much it will cost you to fix? Wonder if you can fix it yourself, if only you knew what it meant?
Enter BlueDriver, a professional quality vehicle scan tool that's simple to use.


The modern smartphone is a wonder of modern technology, and in combination with the carrier network can allow you to make calls from the densest urban jungle to Mount Everest. But despite the amazing global coverage of the carrier networks, sometimes it just isn't enough.
This is when you need to rely on satellite coverage. And believe it or not, you can add satellite capability to your existing iPhone or Android smartphone. Yes, that's right, you no longer need a dedicated satellite phone. What you need is a Thuraya SatSleeve.


A smartphone or tablet opens up a world of possibilities. You can take photos, control drones, make payments, and, if you're old-school, make calls and send messages. But here's something truly amazing that you can do with your iOS or Android device, and it'll only cost you as little as $75 - transform your device into a portable ECG heart monitor for you, your family and friends, or even your pet.
The device you need is the AliveCor heart monitor. This, when combined with the FDA-cleared app, can display ECG rhythms as well as being able to differentiate between a normal sinus rhythm and one showing atrial fibrillation (AF). All you do is place your fingers on the pads and the device does the rest.

Cleaning up your PC the easy way

 Cleaning up your PC the easy way

people hate the idea of sorting out Windows PCs for their friends and relations. Maybe I'm odd, but I enjoy it
Happily, things have changed dramatically in the past five years or so, thanks to the death of Windows XP. That used to provide real horrors. But in my experience, PCs running Windows 7 and later versions rarely have serious problems, and the ones they have are almost all browser-based. Replacing an infected browser is a lot easier than sorting out a compromised operating system,
It's a good idea to keep a small suite of tools installed on a USB thumb drive. Historically, these have included Software Internals' Process Explorer and Autoruns, HiJack This, CCleaner, Malwarebytes Anti-Malware software, Kaspersky's TDSSKiller and a trial version ofHitman Pro. Today, many common tools have been replaced by SlimCleaner Free.
Of course, some malware can stop you from running anti-virus software, even from a thumbdrive, and no doubt some can hide from MBAM and/or Hitman Pro, but I've yet to encounter these beasties in the field. Most common malware harvests "low hanging fruit". Hundreds of millions of people don't keep their software up to date, and their PCs can be attacked using exploits that are months or even years old. Why make the effort to break in when so many people leave doors and windows open?
After a quick scan with MBAM, check that your relative's PC has working antivirus software (I might install Avast), that the firewall is turned on, and that Windows Updates are automatic. Windows tends to nag people to do this, so I find the operating system is usually up to date.
However, it's a good bet that there are several vulnerable third-party programs on these PCs, and it's important to deal with them. SlimCleaner can do this as well, but I usually installSecunia's Personal Software Inspector (PSI): it finds more stuff.
Scan the PC with PSI and it will find all the common software that needs updating, including any Windows code that hasn't been updated. (Windows updates sometimes fail.) The results page provides links to updates, so you rarely have to hunt the web for them.
Watch out for Oracle's Java. It's important to uninstall all versions except the current one, because the old copies are still a security risk. Ideally, I'd uninstall Java completely, but some people need it, perhaps to run games such as Minecraft.
PSI runs a weekly scan, which is too much for most people. However, I encourage them to check PSI after Windows has updated on the second Tuesday of each month.
SlimCleaner's main purpose is to list all the software installed on a PC and show its community rating on a traffic-light system from red to green. Removing unwanted software, including crapware, is one way to reduce the attack surface. However, it now includes Hijack Log, cloud-based anti-virus, tools for cleaning web browsers, seeing what's loaded when the system boots, checking/defragging/wiping disks, finding duplicate files and other things. It has become the Swiss Army knife of clean-up software, always bearing in mind that you should download it directly from SlimWare not from Download.com
If they're using Microsoft's Internet Explorer, this is a good time to install Firefox (or, if you must, Chrome) and make it the default browser. Along with Firefox, I usually install Ghostery and uBlock Origin to cut down the tracking and block ads. However, if they use a commenting system such as Disqus or Livefyre (used on ZDNet) then it's important to whitelist it. Most websites should keep working, but people can always switch back to IE for ones that have problems.
Otherwise, check that the PC has at least two admin accounts - every PC should have one spare - and that different people have different accounts. Point out that Standard accounts are safer and that children should be given children's accounts, not admin accounts. 
If they are using Windows 8/8.1 or 10, I show them how to use a 4-digit pin to log on. This avoids having to type in the complex password they should be using with their email account. I also show them how to refresh or reset their system from the built-in recovery system, which can be an easy way to solve a lot of problems.
Some odd people don't like apps, but I encourage Windows 10 users to download software from the Windows Store and to use apps in preference to traditional Windows programs. Apps written to Windows Runtime run sandboxed, so they are much safer than traditional Win32 apps. They are also easier to install, update and uninstall, just like Android and iOS apps.
Windows 10 includes several useful apps, and there are plenty more in the Windows Store.
In one or possibly two cases, you may want to offer remote assistance. Windows Remote Assistance is already built in, and it's not hard to use. (Just type remote into Windows' search box.) However, many people prefer to use the free, open source TeamViewer.
In cases of extreme incompetence, you may want to get them off Windows and onto, for example, Linux Mint 17.3. However, I've not yet found a close friend or relative who is interested. Even if they were, I expect there would be some Windows thing they can't do without, such as Apple iTunes, Microsoft Office, their favourite games, or some of the old Windows Live Essentials programs for email, photos or videos. Windows Photo Gallery is indeed excellent and I'll be sad to see it go.
Two words to keep in mind are educate and automate. If you can get people to adopt better computing habits, they're less likely to run into problems. And the more processes you can automate, the less they have to worry about. Both contribute to reducing the need for future support.
As Benjamin Franklin said, "An ounce of prevention is worth a pound of cure."

How to secure Windows 10: The paranoid's guide

No comments :
Worried sick over Windows 10's privacy settings? There's a lot you can do to lock them down, but you will lose some functionality along the way.

Just because you're paranoid doesn't mean that they're not out to get you.

With some work you can lock Windows 10 privacy settings down but at the cost of some functionality.
That said, I think some people's fears about Microsoft looking over your shoulder are over-the-top. And, I speak as someone who looks at Microsoft with a great deal of suspicion.
What you need to realize is that Microsoft has made Windows 10 both a desktop and a cloud operating system. Adding cloud functionality means that when you run Windows 10 you'll be sharing far more information with Microsoft and its partner customers than ever before.

For example, while Windows 10 doesn't have a keylogger it does collect your keystrokes and voice to improve spell-checking and voice recognition. Before having a fit about this, keep in mind that every cloud-based software-as-a-service (SaaS) program does this to one degree or another. Google Docs, Apple's Siri, Office 365, whatever -- they all collect not just your final words but every keystroke and spoken syllable that went into making those words.
It's another case with Wi-Fi Sense. You don't need to be afraid that Wi-FI Sense will let any of your Skype, Outlook, or Hotmail contacts use your Wi-Fi network without your permission. Yes, Wi-Fi Sense is on by default, but take a closer look. It doesn't permit anyone to use any of your Wi-FI networks without your specific permission.


Still don't trust these new "features?" I can't blame you. This is not the Windows you've known and used for years. This is a Windows that exists both on your PC and in Microsoft's cloud. Here's how to lock down Windows 10 and make it more of a PC-centric operating system.
First, head to Settings/Privacy. There you will find no fewer than 13--count 'em, 13--different privacy settings screens. The major settings are under the 'General' screen. The other screens are concerned with which apps can and can't access your calendar, camera, messages, microphone and so on.
On the General screen, you'll see your Advertising ID. This is your unique ID number. Think of it as being like a web cookie and you won't be far wrong. It's used to identify you to Windows apps advertisers. So, for instance, if you're a big Dallas Cowboy fan, you can count on seeing ads for Cowboys gear. Microsoft claims it doesn't link this ID with your name, email address, or other personal information.

Of course, they don't need to. Any company that does modern web advertising is going to have you pinned down with our without this ID. Welcome to the 21st century. Personally, I've already turned it off.
If you're still concerned about keylogging, head to Privacy/Speech, inking & typing. Think long and hard about whether to use Microsoft's "Getting to know me" improvements. Steve Hoffenberg, VDC Research's Director of IoT & Embedded Technology worries, for instance, that these Windows 10's "features" violate Health Insurance Portability and Accountability Act (HIPAA) privacy requirements. If his fears are valid, this means medical offices and health insurance companies should turn off this Windows 10 setting.
I doubt he's right, but I'm no lawyer. Even so, were I working with transactions that fall underSarbanes- Oxley (SOX)Gramm-Leach-Bliley (GLB), or HIPAA, I'd turn off this feature, and its related setting, "Windows 10 Input Personalization." Better safe than sorry.
Be aware, however, that if you turn off the "Getting to know me," this will also disable both dictation and Windows 10's voice-activated assistant Cortana,
Next, you'll want to use "Manage my Microsoft advertising and other personalization info" to decide on whether you want advertisers to show you ads based on your browsing history and interests. Better still, skip that page and head directly to Microsoft personalized ad preferences and opt out of everything. Advertisers already know far too much about me as it is.
You'll also want to look at each individual setting page to make sure that Microsoft and Windows have just as much access as you feel comfortable with. So, of course you want Windows' Calendar app to access your calendar data (obv) -- but share it with advertisers via App connector? I don't think so!

Be sure to go through each setting even if you don't think they'll matter. By default, each and every privacy setting is set to give Microsoft and friends the maximum possible access. This is not a good thing.
Moving on: Head to the Location settings and turn them off. While your PC probably doesn't have a GPS like your smartphone, you'd be amazed at how accurately your location can be pinned down using Wi-Fi access points and IP address. I've never been comfortable with letting anyone track me and I turn location off on every device I own except when I need GPS directions.
If you turn off location services, though, you won't be able to fully use Cortana. That's annoying because Cortana is one of Windows 10's best features. It's helpful to just ask your computer a question and get useful, personalized answers. But like its older relatives, Siri and Google Now, for Cortana to show to its best advantage it needs access to an enormous amount of personal data. For instance, Cortana must have locations services on. Cortana also watches pretty much everything you write, say and do on your PC. For example, it keeps track of your flights by detecting "tracking info, such as flights, in messages on my device."
That's both incredibly handy and incredibly creepy. If you find it more disturbing than useful, head to Cortana's settings, under Cortana and Search, and turn off everything there that doesn't pass the smell test. Cortana will be less useful, but you'll get more privacy.
Another approach to locking down Windows 10 is the open-source "Disable Windows 10 Tracking." This brand-new program claims that it disables telemetry collection, certain Windows services, and other tracking. At this point, this is a bare-bones program and only Windows experts should use it.

Still not private enough for you? Then don't use Windows 10, Chrome OS, iOS, Android, or any other system that's tied closely into the cloud. Instead, use Linux as your desktop operating system. By default, Linux is the only mainstream operating system that still relies primarily on true desktop apps.
Not ready for such a radical move? Well, actually, it's not that radical. If you can use Windows, trust me, you can use Linux distributions such as Ubuntu 15.04 or Mint 17.2.
Otherwise, get busy locking down Windows 10. Good luck.

How to remove "Warranty Void If Removed" stickers without voiding your warranty

hey Readers,

Want to fool Manufactures by voiding Warranty of any electronics goods,Want to get inside one of your electronic gizmos but there's a "Warranty Void If Removed" stickers standing between you and the freedom to tinker? Fear not, for there are ways and means that will allow you to take back ownership of your devices.


Want to get inside one of your electronic gizmos but there's a "Warranty Void If Removed" stickers standing between you and the freedom to tinker? Fear not, for there are ways and means that will allow you to take back ownership of your devices and remove that sticker without damaging it.
To show you how to do this I'm going to enlist the help of a couple of international YouTubers. Both of these guys really know their stuff and if you got some time to kill I suggest you have a look at some of their other videos. I guarantee you'll pick up a lot of useful hints, tips, and information while at the same time being entertained.
First off we go down under to Australia where Dave Jones fame offers up this trick where you remove the sticker using a little bit of heat and a static shielding bag. It takes some patience but it does work.
If using a static shielding bag feels a little bit too homebrew for you then what you need is a DIY Teflon knife specifically built for the job. For this we next visit Canada where Chris, who runs the AvE channel on YouTube, will how us how to make one and how to use it.
WARNING: This channel is NSFW due to the colorful language that can be thrown around, and I'm in no way responsible for your use of the phrase "skookum choocher" if you watch more than a couple of Chris's videos.
Finally, let me throw a tip into the hat that can save you should you bust a "Warranty Void If Removed" sticker. Have a look on eBay for a replacement. Chances are good that if the sticker isn't proprietary (that is, it's not emblazoned with the company's name or whatever), you'll be able to find a replacement that's a close enough match.

Microsoft: Windows 10 now running on more than 110 million devices

As we know after give free upgrade to windows 10 now the company claims That MicrosoftWindows 10 now running on more than 110 million devices


Microsoft's Windows 10 operating system is on more than 110 million PCs and tablets, according to company officials, up from 75 million just over a month ago.

Users have activated more than 110 million copies of Windows 10 since Microsoft began rolling out the operating system on July 29.
That's the latest claim by company officials, as of October 6.
At Microsoft's Windows 10 devices launch in New York City, Windows and Devices chief Terry Myerson disclosed the updated figure.
On August 29, Microsoft execs said Windows 10 was on more than 75 million devices, which was up from the 14 million figure -- the number of copies activated in the first 24 hours the OS was available.
Back in August, when I asked, Microsoft said it was disclosing the number of Windows 10 copies activated by users, not the number of copies of the OS it had sold into the channel.
Microsoft began making Windows 10 available to Windows 7, 8 and 8.1 users as a free upgrade for consumers and some business customers on July 29. Those who don't qualify for the free upgrade and are not covered by a volume license with Software Assurance can opt to buy Windows 10 Home for $119 and/or Windows 10 Pro for $199.
Microsoft has released Windows 10 for IoT, but still has not made available Windows 10 Mobile, the version of Windows 10 for Windows Phones and small ARM- and Intel-based tablets.
Microsoft officials believe Windows 10 will be installed on one billion devices by2018, officials said earlier this year.

Dell and EMC: A big buyout

No comments :

Hello Readers
Today's Big news is 


Dell and EMC would merge in what would be one of the largest leveraged buyouts. Strategically, the deal makes sense, but there's a catch. Dell and EMC still lack a public cloud story in a hybrid market.

Dell is reportedly planning to offer more than $27 a share for EMC in what would be a massive leveraged buyout.
According to CNBC, the deal would be about a week away and Dell has to line up $40 billion in financing. The general idea is that Dell would buy EMC and keep control in VMware.
EMC has been evaluating strategic alternatives and looking at everything from a reverse merger where VMware, which is majority owned by the storage giant, could buy EMC, to bringing VMware in-house.
The rationale for the EMC-Dell combination is straightforward:
  • The companies would have more scale and be able to play in nearly every aspect of the data center.
  • Dell would get real software assets via ownership of VMware and EMC's capabilities.
  • The combined companies would have a better converged infrastructure story since EMC also has VNX.
  • Both companies could cobble together a decent services organization to better sell hardware and software bundles.
Of course, there's a catch. The combined EMC-Dell would be massive yet lack a public cloud story. EMC and Dell would be all about building private clouds and hybrid architecture. The big hole EMC and Dell would have is a public cloud to combine the private infrastructure. IBM has SoftLayer.
In other words, EMC and Dell could combine in one of the largest leveraged buyouts ever and still be run over by hyperscale cloud providers such as Amazon Web Services and Microsoft and lack the hybrid play that IBM touts. HP Enterprise would aim to pounce on the fear, uncertainty and doubt surrounding a Dell-EMC merger. Much of that FUD would revolve around the combined EMC-Dell's ability to fund innovation with what will be a heavy debt load.
Dell went private to transform from a reliance on PC to more soup-to-nuts infrastructure, services and software. Financially, the time is right for Dell to ponder a leveraged buyout due to low interest rates. What's unclear is whether Wall Street has the appetite to fund a leveraged buyout that large at a low rate.
It wouldn't be crazy to Cisco to ponder an EMC purchase too. EMC with VMware would be a strong asset for most of the IT megavendors.
Should Dell pull off an EMC merger, it's clear that the IT vendor landscape would shift. HP Enterprise, which is about to split from its PC and printer sibling, is downsizing to be more nimble. EMC and Dell would go in the opposite direction.
Jefferies analyst James Kisner noted the scale from EMC and Dell would likely mean more consolidation.
We see increased scale as the main benefit from a combination. Dell and EMC are increasingly competing with the likes of Amazon, Google, Microsoft, and others that have deep pockets; becoming larger would make Dell and EMC of greater strategic importance to their customers. Secondly, a combination would allow Dell+EMC to provide a more compete private cloud stack. While Dell is not as significant a player in networking as HP Enterprise, Dell's server position and software could prove useful (servers could be used in hyper converged appliances, for example). We believe enterprise customers want their private cloud vendors to be able to provide an easily integrated and scalable private cloud stack that ideally is also interoperable with other vendors' stacks. This combination would at least increase EMC's breadth.
